【摘要】 “基于WEBGIS的水资源管理信息系统”是受长江水利委员会委托开发,是长江流域信息化建设的重要项目。取水口管理是长江流域水资源管理系统中的一个比较难于分析的子模块。文章探索如何把WEBGIS的功能与管理信息系统(MIS,Management Information System)结合并应用到水资源管理系统中,分析和挖掘地理信息系统应用到水资源管理系统中的优势和应用前景。本文依据WEBGIS的实现技术及特点,分析了ArcIMS的体系结构及其运行机制,通过基于ArcIMS9平台并结合JS, JSP等技术,提出一种新的具有多层结构的WEBGIS解决方案,并结合具体实例阐述了其在水环境管理信息系统的实现。结合水环境管理信息系统的需求,给出了基于WEBGIS的水环境管理信息系统的功能结构和体系结构。采用Apache+Tomcat作为Web服务器、ArcIMS作为地图服务器完成了系统功能设计,实现了网上数字地图的处理、传送,以及基于地图的水环境查询、评估、统计、分析、排放污染总量和污染源的控制。实现对水环境的综合开发、合理利用、积极保护、科学管理。系统通过对ArcIMS的二次开发,对客户端地图浏览器的定制,实现了浏览器端对相关地图进行放大、缩小、平移等功能;分图层浏览、显示,并以图上点击、输入监测站名、输入地名、给定范围等多种方式查询监测站信息;图上监测信息可由客户端选择组合标注;可进行图形、属性的双向查询;可动态显示监测数据的统计曲线图和柱状图。更多还原

【Abstract】 “Management Information System of Water Environment Based on WebGIS”, is a software project commissioned by the Yangtse valley water resources protection bureau. The management of water resource gap, is a special sub system in the whole system. The study object of the paper is exploring how to combine WEBGIS with Management Information System and how to apply them in Management Information System of Water Environment, and analyze the advantage and application foreground of WEBGIS.This paper introduces the technologies and characteristics of WEBGIS. It analyses the system framework and running mechanism of ArcIMS. Based on ArcIMS 9.0, integrated with the technology of JS and JSP, an architecture of WEBGIS is put forward. The Water Environment Manage Information System illuminates the realization.This paper presents the architecture of Management Information System of water environment based on WEBGIS meeting the need of the system. By adopting the Apache+Tomcat as Web Server and the ArcIMS as map server, the system implements map processing and transmission on Web. In addition to these, it provides water environment query, evaluation, statistic, analysis, control of pollution gross and pollution source based on the figure to achieve the synthetize development, reasonable use, positive protection and scientific management.Functions such as magnifying, lessening, translating map in user’s browse by the way of Secondary exploitation to ArcIMS and customization to user’s map browse are realized. It can be browsed and displayed by layer, and be queried by means of clicking on the map, inputing names of watch point or some place and giving the boundary. Informations on the maps can be labled in the user’s browse. Attributes of map can be queried, and live data can be shown both in graph and bar chart.更多还原
